Frequently Asked Questions (FAQs)

• What is organic compost and why choose it? Organic compost is decomposed plant/animal matter, enriching soil naturally with nutrients and microbes—better than synthetics for eco-health and long-term fertility.
• How much organic compost for a vegetable garden? Mix 20-30% (2-3 inches) into top 6-12 inches of soil; 1 lb/sq ft at 1 inch for topdressing.
• Does organic compost attract pests? Rarely if fully composted (low-odor options like Charlie’s); cover fresh applications to deter flies.
• Can I use organic compost for indoor plants? Yes, use screened, low-odor compost (e.g., R&M Organics) mixed 10-20% with potting soil.
• How to test compost quality? Check for dark color, earthy smell, no visible waste; lab tests confirm NPK and organic matter (>50%).
• What’s the difference between compost and manure? Compost is fully decomposed (stable nutrients); manure is rawer, needing composting to avoid burns—compost is safer for direct use.
